[occi-wg] Votes: XML vs. JSON vs. TXT

[Krishna Sankar (ksankar)]

+1 for JSON. I could do no better then what Andy has written eloquently.

Cheers

|JSON is fine with me and is a good target output format for the 1st rev
|of OCCI. However it's the model that is the important thing for me.
|
|In my view* there's a protocol, a data structure and an on-the-wire
|format.
|
| - Like Alexis said, the protocol is "a sequence of behaviours" - how
|the communication happens and is mediated. This is our set of verbs.
|This is, for example, can be mediated by REST.
| - The data structure is the model. This is how each noun is related to
|each other and what attribute is part of what noun. Models can be
|somewhat ephemeral, often expressed as programming language agnostic
|UML, BNF, XSD or indeed using a programming language e.g. Java, C etc
|(but then model portability is limited).
| - On-the-wire format is what we're currently talking about (JSON, XML,
|TXT). The raw output of our model.
|
|The latter 2 can be compared to a compiler - the model is the language
|and along with a frontend, it generates an AST (an object graph). With
|the object graph, it's easy to output binary machine code via a backend
|on whatever platform required. This is similar to if I was to code my
|model in say Java, instantiate an object graph and then render that
|graph using any serialiser. For example using XStream[1] I can output
my
|model using XML and JSON (the machine code).
|
|So currently in my view there's consensus around a protocol - REST
(hope
|that's fair to say); consensus forming on data structures; confusion on
|on-the-wire formats.
|
|If we don't finalise our data structures (model) we won't resolve the
|on-the-wire format quickly.
|

|I'd like to conduct a straw poll of members on this list.

|
|and that does make me question our (/my!) current proposal of multiple
|formats with automatic conversion.
|
|
|I'd like to conduct a poll of everyone on this list considering the 3
|format
|options:
|
|- XML
|- JSON
|- TXT
|
|Please can people reply to this post casting a single vote for their
|most
|preferred of these three formats. I'll tabulate the responses. If
|there's a
|clear winner, we should probably go with it alone. If there's a split,
|then
|multiple format support as we're currently proposing may be the answer.
|
|
|I'm going to start the counts with the clearly stated opinions which
|I've
|seen to date (listed below). If I'm misrepresenting anyone, then please
|also reply and I'll change your vote in my count.
